Illinois minimum liability is 25/50/20: $25,000 per person bodily injury, $50,000 per accident and $20,000 property damage. Illinois is an at-fault state with no PIP requirement, but mandates both uninsured motorist (UM) and underinsured motorist (UIM) coverage at matching limits. Every minimum policy in Illinois covers uninsured and underinsured drivers.

Illinois minimum coverage includes required UM/UIM at 25/50/20. The most expensive full coverage among analyzed providers is Allstate at $144/month; Allstate was analyzed but excluded from top-five tables as lower-cost providers rank ahead of it in every category.

Auto-Owners is cheapest for young adult drivers on a standalone policy at $164/month, $30 less than GEICO at $194/month (Quadrant Information Services). GEICO is cheapest for adult drivers, and the ranking reverses for teens. Families using GEICO without getting an Auto-Owners quote overpay by $360 a year for young adult coverage.

On family policies, Auto-Owners is cheapest at age 16 with a $5/month gender gap ($319/month for female drivers, $324/month for male drivers). Teens under 18 can't legally purchase auto insurance without a parent or guardian as a co-signer in most cases, so these rates reflect family policies. 

Travelers is cheapest from age 17 through 24 for both genders. At age 25, Auto-Owners returns as cheapest for both men and women at an identical $147/month. Car insurance rates by age show how rates shift across age groups.

Auto-Owners is cheapest in three high-risk categories: speeding tickets ($82/month), at-fault accidents ($94/month) and texting while driving ($73/month, the same as its clean-record rate). For DUI, the pattern reverses: Travelers is cheapest at $129/month and GEICO is the most expensive of the five analyzed providers at $147/month. COUNTRY Financial is cheapest for bad credit at $164/month, $34 less than GEICO at $198/month. These gaps illustrate how high-risk car insurance in Illinois rates shift by violation type.

Most violations affect rates for three years; DUI convictions remain on record longer. After a DUI, Illinois requires an SR-22 filing to prove you carry the state's minimum coverage.

GEICO is cheapest in five of 10 analyzed Illinois cities; Auto-Owners is cheapest in five Chicago suburbs (Aurora, Elgin, Joliet, Naperville and Waukegan). Chicago is the most expensive analyzed city at $98/month; Champaign is the cheapest at $58/month, a $40/month ($480 a year) gap. 

Chicago has among the highest traffic density in the Midwest, elevated vehicle theft rates and a high concentration of uninsured drivers. Champaign is a university city with lower claim frequency and minimal congestion outside event days.

The Chicago suburbs, including Aurora ($76/month), Elgin ($77/month), Joliet ($78/month), Naperville ($73/month) and Waukegan ($76/month), cluster between $73 and $78/month, all led by Auto-Owners rather than GEICO. Compare car insurance options side by side.

A driver who moves from Champaign ($58/month with GEICO) to Chicago ($98/month with GEICO) pays $40/month more at the same insurer and should verify whether Auto-Owners undercuts GEICO in their specific ZIP code.

Two things make Illinois's minimums worth reading closely. The liability limits of 25/50/20 have bodily injury at the national baseline, and a $20,000 property damage floor that falls short of what most vehicles cost to repair. What stands out is what Illinois requires on top of that. The state mandates uninsured motorist coverage at the same 25/50 limits, something fewer than half of states require. If a driver with no insurance causes a crash, you're protected without having to opt in.

The liability numbers themselves still have hard ceilings. Chicago's traffic volume may result in the routine exposure of multi-vehicle crashes with more than one injured party. That $50,000 per-accident cap divides across everyone involved. Your own medical bills and vehicle are never covered at minimum regardless of fault.

Here's how Illinois's required limits compare to the rest of the country, and where the coverage ends.
